Characteristics of the course of canine cystisosporosis as part of mixtinvasions

Abstract

Dog breeding is a branch of animal husbandry that involves the breeding of dogs of cultural breeds for use in various branches of the national economy, sports and the army. At the same time, the efficiency of dog breeding, their health and veterinary welfare are affected by diseases of parasitic etiology, in particular protozooses. Such infestations include cystoisosporosis, which causes economic damage to dog breeding. However, in dogs, parasitoses often occurs in the form of mixed invasions, where the causative agents of protozooses and helminthiases can be co-members, which is significant when prescribing treatment and increasing the effectiveness of treatment measures. Dogs were examined by coproovoscopic flotation methods for the presence of parasite oocysts/eggs. The conducted studies established that cystoisosporosis occurs more often in the form of mixed invasions (70.8 %), less often in the form of cystoisosporous monoinvasion (29.2 %). Cystoisospores were helminths of the intestinal tract: cestodes – Dypilidium caninum and nematodes – Trichuris vulpis, Toxocara canis and Uncinaria stenocephala. A total of 10 types of mixed invasions were detected in dogs infected with Cystoisospora spp., where two-component infections were found in 71.9 % of dogs, three-component – in 25.1 %, and four-component – in only 3.0 %. Cystoisosporous-toxocarous (28.7 %) and cystoisosporous-trichurous (24.6 %) were more often diagnosed from two-component associations. Of the three-component associations, simultaneous parasitism in the body of dogs with cystoisospores, toxocares, and trichurises (9.6 %), cystoisospores, toxocares, and dipylidies (7.8 %) was more often diagnosed. Four-component associations are represented by two varieties, where the co-members were: cystoisospores, toxocares, trichurises and dipylidies (1.8 %), cystoisospores, trichurises, dipylidies and uncinaries (1.2 %). Most often, co-members of Cystoisospora spp. were Toxocara canis (53.3 %) and Trichuris vulpis (39.5 %), less often – Dypilidium caninum (24.6 %) and Uncinaria stenocephala (13.8 %). The obtained results make it possible to take into account the peculiarities of the course of cystoisosporosis in dogs for the effective implementation of treatment and prevention measures.
